SLED.

SPECIFICATION forming part of Letters Patent No. 281,372, dated I'uly17, 1883.

Application filed April 14, 1883. (No model.) Y

.To all whom, it may con/cern).-

Be it known thatI, HENRY KELLER, a citizen of the United States,residing at Sauk Centre,in the county of Stearns and State of Minnesota,have invented certain new and useful Improvements in Sleds; and I dodeclare the following to beafull, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letwhich form a part of thisspecification.

My invention relates to improvements in sleds of a class usuallyemployed for hauling logs, and has for its object to provide asubstantial, strong sled, and to furnish convenient means whereby thebeam may have the rocking motion desirable in sleds of this class.

In the drawings, Figure l Vis a vertical longitudinal section of arunner knee and beam ofa sled constructed according to my invention.Fig. 2 is a top view of a part of the beam, and Figs. 3, 4, and 5 aredetail views, all of which will be described.

The runner A is constructed in ordinary manner, and is provided,preferably, with a mortise or opening leading from one .side,with inwhich a I arrange a nut, a, to receive the lower end of the standard,hereinafter described. This nut is arranged soit can be turned in orderto release the said standard. When so desired, however, a threadedsocket may be formed in the top of the runner and the nut a be dispensedwith. The knee B is made, preferably, of iron, and is secured to therunner A by bolts b b, as shown. The top-of this knee is made broad andflat to provide a good bed for the beam, which rocks thereon, as will bedescribed. A standard or bolt, C, is projected above the knee B, and itsshank c is passed down through the said knee, and its lower end isthreaded and turns into the nutc', or other suitable socket formed intherunner to receive it. The juncture of the standard C and its shank cforms a shoulder, c, which rests on the knee, so that the standard issupported by the knee and by the runner. A head, c2, is 'preferablyformed on the upper end-of the standard, for the purpose hereinafterdescribed.

The beam D is constructed with the mortises d formed through it near itsends. mortise is made the same at both ends, elongated, as shown inFigs. l and 2, and midway its ends it is contracted to a diameter corre?sp onding approximately to the standard which is passed through it. Thewidth of this mortise is' preferably uniform froml end to end, and aboutequal or slightly larger than the standard, and the elongation is madein a line parallel with the runners or direction of motion of the sleds.

In order to strengthen the beam I provide iron or other metallic boxes,d d', corresponding to the shape of the opposite ends of the mortise,which are driven into position, as shown in Fig. l, and provide astrong, smooth, and lasting bearing for the standard.

In setting up the sled the knee is secured in position and the beam isplaced thereon, and the standard is passed down through the inortise dand turned to its bearing in the runner, and the sled is ready for use.The connection between the standard and the beam permits the latter tohave a free rocking motion, the central or contracted portion of themortise being the pivotal point. The edges of the beam are rounded toreduce its friction on the knee. The top or head c2 on the standardholds the beam from slipping off the standard. This is not absolutelynecessary, as the standard couldbe made high enoughto prevent allliability to such mishap, but it is desirable. Where so desired,however, short chains could be fastened to thel knee and to the beam onopposite sides of the mortise, so as to hold the beam from slipping offthe standard, and the head c2 could be dispensed with.

I prefer to use the knee constructed as described; but it willbcunderstood that knees This of other construction could be employed, and

that, if so desired, the runner could be extended up high enough toavoid the necessity of a knee and thebeam could be rested directlythereon, also, that the standard could be projected up from the knee orthe runner and supported suitably in other manners than as hereinbeforeset forth, though the construction before described is preferred.

Having` thus described my invention, what I claim, and desire to seeureby Letters Patent, 1s-

1. In a sled, the beam constructed with the inortise having' its outerends elongated and its middle portion contracted, and a standard or boltpassed through said mortise and seeured or made fast in position,substantially as set forth.

2. In a sled, the Combination, substantially as hereinbefore set forth,of the runner, the

knee, the beam constructed with the;4 mortise having its outer endselongated and its middle 15 portion Contracted, and the standard passedthrough the said mortise and the knee, and

' having its lower end removably secured to the runner, substantially asset forth.

In testimony whereof I affix my signature in 2o presence of twowitnesses.

HENRY KELLER.
